While git has a clean command to remove untracked files, it seems subversion doesn't support such a command.
I found Patric Fornasier's Blog explaining how to remove unversioned files in subversion and I was very happy, but it seems theat xargs can';t handle spaces in the file names and so chokes.
So I went ahead and created a simple script to handle whitepsace in the file names based on Patric's piping of commands.
#! /bin/sh
# svn stat --no-ignore | grep ^\? | cut -b 8- | xargs rm -rfv
FILES=`svn stat --no-ignore | grep ^\? | cut -b 9-`
SAVEIFS=$IFS
IFS=$(echo "\n\b")
for f in ${FILES}
do
rm -rfv "${f}"
done
IFS=$SAVEIFS
